Pietersen's future has shrouded England for some time, with debate raging even since the record runscorer was discarded from the set-up following the Ashes whitewash in Australia.

England managing director Paul Downton described Pietersen as "disconnected" from the team and the batsman was culpable in an apparent coup which ended Moores' first spell as England coach in 2009.

Broad thinks England must now move forward under Moores, who was reappointed after Andy Flower's resignation.

"I wasn't overly aware of a lot of grumblings going on in Australia," said Broad, who was speaking at the launch of Royal London's One-day cricket sponsorship at the Royal Opera House.

"It's obviously a new era and you wouldn't have thought Mooresy would be coach if KP would've been (playing); well, he wouldn't be, would he?

"Everything happens for a reason and I think Mooresy is the right man to bring a lot of energy and passion back to this England side."

Asked if he expects Pietersen to pop into the England dressing room during the first test of this summer against Sri Lanka, which begins on June 12, Broad said: "It would surprise me if he nipped in.

"Of course he'd be welcome, but, actually, there's a sign on the door at Lord's. It says: 'Anyone welcome at the captain and coach's discretion'. So...

"Fortunately I won't be captain at Lord's and it won't be my call."

Moores was undermined by senior personnel during his first spell as coach from 2007 to 2009 but has the full backing of the squad this time round.

Broad expects Test captain Alastair Cook, who undertook a period of introspection after the Ashes to work well with the new coach.

Broad, who was given his Test debut by the former Sussex and Lancashire coach, added: "I think he'll really complement Pete Moores. I'm glad he's decided to stay on, I'm glad he's given the opportunity to stay on.

"Mooresy will get the best out of young players and senior players moving forward.

"I'd expect to see the side play with a lot of passion and enthusiasm this summer, which I'm not out of place in saying was missing in Australia.

"There's a lot of enthusiasm about him coming back into the set-up. Just having a couple of little meetings with him you get how excited, how logically he talks about the game of cricket.

"I'd worked with him on the national academy and he made a middle practice at Loughborough University feel like a test match.

"He has the ability to enthuse players. Just from chatting within the guys since his appointment, he's got the respect of everyone around now and that's the only important thing.

"Hopefully in a year's time we can play the sort of cricket where we won't even remember last winter."

Broad expects Ashley Giles, who was limited overs coach and overlooked as Flower's successor, to respond from the disappointment.

"I feel sorry for Gilo," the Nottinghamshire all-rounder said.

"I worked closely with him this winter, he's had a bit of a rough ride in the fact he never had his full side out and still got us to a Champions Trophy final.

"There's no doubt he'll go on to be a coach, domestically or internationally, of a high calibre."

He also insists Flower's performance should not be judged on the latter stages of his reign.

"In Australia we did some frustrating things as a team, but the four years previous to that we did some fantastic things as well," Broad said.

Broad hopes to be fit for the Sri Lanka series after a niggling knee injury.

He has returned to running this week, will bowl next and plans to play in Nottinghamshire's County Championship match with Durham, which begins on May 25, and at Sussex.

Broad added: "Missing the Sri Lanka one-day series gives the opportunity to guys, 15 ODIs away from the World Cup.

"It also gives me a really good chance to get my knee a bit stronger and play some Championship cricket before the test matches."

Despite the impact on his body, Broad aims to continue to play all formats of the game.

Broad, who believes a decision on the Twenty20 captaincy can wait, added: "I want to be available for Twenty20 cricket moving forward, but whether I will be able to play all the Twenty20s with such a busy 18 months ahead remains to be seen.

"It's a conversation that's not been had and doesn't need to be had until later in the summer.

"I've always said Test cricket's the absolute pinnacle for me and you'd prefer to miss three hours' work than five days."
